If-Else Logic

[Joe]

Is there a way to implement If-Else logic in the Hack Assembly Language?  I've used a while loop for Fill.asm to fill the screen, but I want to use some kind of conditional logic to check and see if KBD == 0 or KBD == 1.

Thanks!

Well, if KBD == 0 at any rate.  Supposedly, that RAM location gets filled with the ASCII value of a key when it's pressed.

This is what the Jump Specification in C-Instructions is all about.  (4.2.3, p.68)
Load KBD into a register and do a conditional jump.
